The QUINT-PS/3AC/24DC/40 is a primary-switched DIN rail power supply unit designed for industrial automation and control applications. It features Phoenix Contact's proprietary SFB (Selective Fuse Breaking) technology, which provides up to six times the nominal output current for 12ms to allow individual circuit protection to react to fault conditions without collapsing the entire DC bus. The unit delivers a stable 24 VDC output with 40 A capacity and 960 W output power from a three-phase AC input or DC input source. It includes comprehensive diagnostics through continuous monitoring of output voltage and current, preventive function monitoring for critical operating states, and adjustable output voltage from 18 VDC to 29.5 VDC. The compact design saves over 50% of space in control cabinets while offering wide temperature range operation and high efficiency exceeding 94%.
